In its general organization, this automatic selector phonographcomprises a vertically reciprocating turntable which constitutes asupport for a plurality of records disposed in stacklike fashion axiallyof the turntable; a selectorelevating mechanism movable at apredetermined time into supporting engagement with those records in thestack immediately above the one pre-selected for play, for elevatingsuch supported records to split the stack and provide an operating spacefor the movement of the tone arm during the playing of the selectedrecords; a tone arm mounted to swing in a definite horizontal plane andpivoted to swing vertically into engagement with the record or to aposition to clear it when the tone arm is returned to its initialposition after playing the record; an elevating mechanism for theturntable which functions to elevate the turntable to varied elevationscorresponding to those of the records selected, and operating at a timeprior to that of the selector-elevating mechanism to bring the selectedrecord at its proper playing elevation, after which suchselector-elevating mechanism splits the record stack and moves it adefinite and constant height, as compared with the elevating mechanismof the turntable which moves the turntable a variable height to efiectand govern the selection; and a plurality of selector members or pushbuttons for simultaneously selecting at the will of the user a pluralityof records section taken on line l5-l5, Figure 12. Figv o be Playedandincluded in a selective control which the working parts of thephonograph are a mounted, and which platform, in practice, is

mounted in a cabinet of appropriate design, the

68 keyed to the shaft 62, and actuated by a clutch lever 69, serves atpredetermined times to clutch the gear 63 to said shaft and accordinglytransmit motion to the cam shai't61. Mechanism hereinafter described, isprovided for automatically shifting the clutch lever to its appliednumeral 3| indicating aportion of the cabinet.

The tone arm, indicated generally at 32, may be of usual constructionand is mounted to assume a definite horizontal plane of movement. Theturntable 33 is mounted on an upright spindle 34 whose lower portion35is keyed or feathered to a revolving sleeve 36 journaled in the base 31of an upright bearing bracket 38 secured to the,

platform. At the lower end of the sleeve 36 is a flanged cap or plug 39which prevents the sleeve from pulling up and also forms a seat forthrustbearings 48 mounted in a case 4| secured to the bracket-base 31.Applied to the sleeve 36 is a driven gear 42 meshing with a drive pinion43 secured to the shaft 44 of an electric motor 45. The upper portion 46of the spindle constitutes a guidepost for the records 41, the latterbeing supported in suitable trays or carriers 48. As shown in Figures'1, 2 and 4, the records are disposed in superposed relation in the formof a stack, being normally directly supported on the turntable, andbeing capable of sliding on the spindle-extension 46 during theselection of the desired record to be played. It will be observed inthese figures that the peripheral edges of the trays 48 slope upwardlyand inwardly, as indicated at 49, whereby resulting shoulders 50 areprovided at the bottom peripheral edges of the trays, the whole stackgiving the appearance, at the peripheral profile, of a series of ratchetteeth, all for the purpose to be hereinafter described. Fixed to thespindle 34 and constituting a support for the turntable is a collar 5|with which the elevating mechanism for the turntable is adapted toengage.

The means for elevating the turntable to variable heights in accordancewith the selected record to be played and for lowering it after play,consists of an actuating 'arm 52 whose outer end is pivoted to a bracket53 rising from the base 30 and whose inner bifurcated endis pivoted todiametrically opposite sides of a ring 54 bearing against the undersideof the collar 5| and having an elongated opening 54 therein. engagingthe spindle-sleeve 36, so that when this arm is vertically actuated itcauses the vertical reciprocation of the turntable. Intermediate itsends "the arm 52 has a' roller 55 which engages a cylindrical elevationgcam 56 fixed on the upper portion of an upright shaft 51 which is drivenat predetermined times in the cycle of operations to elevate theturntable to different record-playing positions. Motion is transmittedto the cam shaft 51 from the motor shaft 44 and spindlerevolving gear 42through the medium of a gear 58 meshing with the latter and mounted onan upright shaft 59 having a bevel gear .68 thereon which meshes with alike gear 6| mounted on a horizontal shaft 62 journaled in suitablebearings applied to the platform 30. Loosely mounted on said shaft 62 isa clutch-controlled gear 63 meshing with a similar gear 64 fixed'on oneend of a countershaft 65 likewise journaled in suitable bearings appliedto the platform and rovided at its opposite end with a worm 6S meshingwith a worm wheel 61 fixed to the lower end of the cam shaft 51. Asliding clutch-collar and released positions to transmit motion to theturntable elevating cam and arrest it at the predetermined elevationcorresponding to that at which the selected record is played.

After the'selected record in the stack is moved by the turntable to itspredetermined playing elevation, and which elevation is variable foreach record because of the fact that the tone arm of the phonographremains at a fixed elevation, it is then necessary to split therecordstack and to elevate those records, above the selected record, asa unit to provide an operating clearance for the movement of the tonearm during the playing of the selected record. By preference, thiselevating of the records to split or dividethe stack vertically isaccomplished as follows:

Disposed at diametrically opposite sides of the turntable for releasableinterlocking engagement with the records to support and elevate themabove the plane of movement of the tone arm are pairs of uprightsupporting arms 18 which at predetermined times are adapted to beautomatically brought into supporting engagement with those recordsabove the selected one to elevate them and again to be automaticallylowered and subsequently released therefrom after the playing of aselected record and before the selection of another record. Each pair ofsupportand pivotally joined at their free ends to the frame 12 and tobrackets 15 rising from the platform 38, as shown in Figures 1 and.2.Also connected to the ends of the web portion of the U-frame 12 aresimilar crossed levers 16 which are pivoted intermediate their ends at11 and are slidingly and pivotally joined at their free ends to theU-frame and to extensions 18 formed on one set of the brackets 15, as.shown in Figure 2. By this construction, as the sets of levers 13 andv16 are expanded and contracted, the record-engaging arm 10 aresimultaneously raised and lowered, as a unit, the levers acting afterthe fashion of lazy tongs. Applied to the pivot 11 of the cross levers16 is a roller 19 which engages a substantially spiral-shaped cam grooveformed in a revolving sleeve or cylindrical cam 8| mounted on an uprightshaft 82 for 'moving the record-engaging arms to and from a constantelevation. Motion is transmitted to the cam shaft 82 from the motorshaft 44 through the medium of the shaft 62 on which the clutch collar68 is mounted. This clutch collar, when shifted to the left, viewingFigures 3 and 5, enages a collar 83 applied to the end of a worm 85loosely mounted on the shaft 62 and meshing with a worm wheel 86 fixedon the lower end of the cam shaft 82. Thus, when the clutch collar 68 iscoupled with the collar 83, motion is transmitted to the cam shaft 82 tocause the crossed levers 16 to expand and contract and accordingly raiseand lower the record-supporting arms I8.

In the lowered retracted position of the supporting arms I8, the toothedrecord-engaging portions 81 thereof assume a definite predeterminedelevation relative to the horizontal plane of movement of the tone arm,the top record of the stack being below that elevation, so that when theturntable is elevated to a predetermined height to play a selectedrecord, the upwardly-facing shoulders of the arm-teeth 81 will be sodisposed as to be in a plane substantially at or somewhat below the topsurface of the record to be played, whereby when the arms I8 are rockedinwardly, they will engage the peripheral edge-shoulder 98 of the recordtray immediately above the selected record and upon expansion of thecross levers I3 and I9 the records supported by these arms willaccordingly be ele-. vated to provide an operating clearance space forthe tone arm. The means for rocking each of the bars II carrying therecord-engaging arms with the peripheral edges of the record trays.

Immediately upon the upward movement of the arm-carrying frame, becauseof the expansion of the levers I3 and I6, the actuating yokes 88 areswung outwardly and the record-engaging arms are swung inwardly intogripping engagement with the peripheral lower edge of the adjoiningrecord-tray, or that record immediately above the one positioned forplay.

The means for governing the selection of the records and the selectormechanisms for controlling the raising and lowering of the turntable aswell as the raising and lowering of those records in the'stack above theselected one for play are preferably constructed as follows:

Mounted conveniently on the phonograph cab-' inet are a plurality ofselector rods 9| having buttons or heads 92 at their front ends whichcorrespond to the number of records in the stack and which extendthrough a face plate 93, the faces of the buttons being suitably markedby number or otherwise to correspond with the records. Flat springs 94mounted on the front wall of the cabinet 3I and engaging the sides ofthe buttons 92 serve to frictionally maintain the rods 9I in theirnormal retracted position,

shown in Figure 8. The selector rods are preferably disposed in tworows, as seen in Figures 6, 7 and 8, and each rod abuts at its inner endagainst a companion upright lever 95 pivoted at 99 and carries anabutment or projection 91 which is adapted to close a companion electricswitch 98, 99 when the companion selector rod 9| is depressed, theswitch element 98 constituting the movable blade of the switch and theelement 99 constituting the stationary element and being common to themovable blades. Each switch is included in an electric circuit forgoverning the shifting of the clutch 68, 69 at a predetermined time,from its operative position, in engagement with the gear 63 to rotatethe counter-shaft 85 and elevate the turntable 33, to its otheroperative position in engagement with the collar 83 to elevate the stackabove the record selected for play. Leading from the button-actuatedblade 98 of each switch, is a wire I88 which is connected to thecompanion post or terminal I8I of an annular row of terminalscorresponding in number to the selector push rods 9I and with which onearm I82 of a two-armed revolvable contact or wiper member I83 is adaptedto engage. The closing of the respective button-controlled switches 98,99 merely serves to prepare or preset the circuit for automaticallyeffecting, at such time as the circuit is fully established in a mannerwhich will hereinafter appear, the playing of the records selected. Itmay be noted here, however, that the circuit to be established derivesits power from the feed wires I 84, I85 to which the drive motor 49 isalso connected. This contact member is fixed on a shaft I88 having agear, I81 thereon meshing with a worm I88 applied to the counter-shaft65 intermediate its ends, as shown in Figures 5 and 10, said contactmember being rotated simultaneously with the drive mechanism controllingthe vertical movements of the turntable. The shaft I86 and the contactmember terminals I8I may be supported or applied to an uprightinsulating panel I8I' rising from the platform 38.

Rotatable with the countershaft 65 is a cam I89 which controls themaking and breaking of a switch II8 included in the circuit of thecontact member I83 and one terminal of which is connected by a wire IIIwith the shaft I88 to which said member is fastened. The relative speedof the contact-arm shaft I86 is such that for each revolution of thecountershaft 99 the contact member I83-travels a distance equal to thatbetween two adjoining terminals MI. The other terminal of this switch isconnected by a wire II2 with an electromagnet II3 whose armature H4 isjoined to a horizontally-swinging arm II5 pivoted at IIB to afulcrum-plate III pivoted to an upright pivot pin H8 and free to swingin a limited path between stops II9. A spring I28 constantly urges thisfulcrum-plate against one of the stops, as seen in Figure 5. Disposedalongside the arm II5 and in edgewise contact therewith to be movedthereby, is a trip arm I2I, which, when the electromagnet H3 isenergized, is swung to a position in the path of a tappet pin I22applied to the hub of the bevel gear 98 of the upright shaft 59. Whenthis pin encounters the trip arm I2l, as shown in Figure 26, it furtherswings such arm into contacting relation with the opposing free end of ashifting bar I23 connected to the clutch-actuating lever 69, and shiftsthe clutch collar 68 out of driving engagement with the gear 63 toarrest the rotation of the countershaft 65 and its associated parts, andbring the turntable to rest at the elevation required for playing theselected record corresponding to that of the depressed push rod 9 I. Aspring I24 serves to normally retain the armature-carrying arm II5 outof contact with the magnet and the trip arm I2I retracted and out of thepath of travel of the tappet pin I22.

ton switch element 88, corresponding wire I88, and terminal post I 8|,contact member I83, shaft I88, wire III, cam-actuated switch II8, wireII2 electromagnet H3 and thence to the common switch element 88.

The projected movement of the trip arm I2I' by the trip pin I22 issufllcient to shift the clutch 88, 59 into clutching engagement with thecollar 83 to in turn transmit motion to the cam shaft 82 to cause thecrossed levers 13, 18 to expand and accordingly raise therecord-supporting arms 18 to lift those records above the one selectedfor play and provide an operating space for the tone arm. Mounted on thecam shaft 82 for controlling the shifting of the clutch to a neutralposition, and arrest the movement of the elevated stack at apredetermined position, is a cam I28 provided in its periphery with acomparatively deep notch I21 and a comparatively shallow notch. I28.Pivoted at I29 alongside this cam in bearing contact therewith is ahorizontally-swinging lever I 38 which is provided with a. recessedportion I3I forming a shoulder I32 for cooperative engagement with oneor the other of the notches I21, I28. At its free end the lever I38 haspivotally connected thereto an oscillatable tie bar or link I33, shownin Figure 5, whose free end is reduced in width to provide a shoulderI34 adapted to abut against the opposing edge of the clutch-shiftinglever 68, said tie bar having its reduced portion guided in a yoke I35formed on the clutch lever. By swinging the tie bar in one direction itsshoulder I34 is moved clear of abutting engagement with the yoke portionI35 of the clutch lever.

By this construction, when the clutch 88, 88 is automatically shiftedout of clutching engagement with the gear 83 and into clutchingengagement with the collar 83, the tie bar I33 is accordingly shiftedwith it to swing the lever I38 in a direction to release its notchedshoulder I32 from the cam notch I21, and accordingly permit the camshaft 82 to revolve to elevate the record-engaging arms 18. A spring I36applied to the tie bar I33 constantly urges the lever I38 toward thecam-periphery and when the arms 18 have reached their maximum height,shown in Figures 1, 2 and 4, the lever automatically swings into theshallow notch I28 of the cam and simultaneously actuates the tie bar I33to shift the clutch to neutral position shown in Figure 5, and therebyarrest the record-engaging arms at the predetermined elevation requiredfor playing the selected record.

Each of the selector-switch-actuating levers 85 is preferably beveled atopposite sides of its upper end, as indicated at I31 to provideabutments against one or another of which a companion spring-pressedball I38 is adapted to en gage for yieldingly retaining such lever inits projected or retracted position. These springplished automaticallyduring the time that the record stack is split and being elevated clearof the selected record to be played, and to this end one of the partsrevolving with the stackelevating cam shaft 82, say the driven gear 88',is provided with a tappet I42 adapted to engage one end of a trip leverI43 pivotedat I44 to the adjoining part of the platform 38. The otherend of the trip lever-engages a laterallyswin ing, spring-pressed toggleor link I45 pivoted to the opposing end of a rock lever I48 fixed on theadjoining end of the journal I41 of a vertically-swinging ball or crankI48 pivotally supported in the endwalls of the bearing frame I48.Slidably mounted on the bail I48 for movement lengthwise thereof is abar I48 for registering contact with the upper end of one or another ofthe projected levers 85; Thus, when the tappet I42 strikes the triplever I43, it causes the rock leverv I48 to rockcin a direction to swingthe bail-l48 forwardly to bring the slide bar I48 into engagement withthe respective lever 95 to restore it and its companion switch element88 to open position;

The means for actuating the tone arm 32 to bring it into play positionover the record selectt ed for play, after the turntable 33 has beenelepressed balls are arranged in a housing I39 applied to the upper endof a bearing frame I48 in which the levers 95 are pivoted and guided innotched portions I4I formed in such frame.

After a given selector rod 8| has been depressed to select a record forplay, it is necessary to restore the companion upright lever 95 from itsselected or projected position shown by full lines in Figure 8 to itsinitial retracted position shown by dotted lines in said figure, suchrestoring operation taking place after the turntable 33 has beenelevated to the play position and simultaneously opening the switch 88,89 associated with such rod. This is preferably accomvated and the stackof records split above the selected one as heretofore described, and forreturning the tone arm to its initial starting position after theselected record has been played, is preferably constructed as follows:

The numeral I 58 indicates the upright supporting post or column aboutwhich the tone arm revolves in a definite horizontal plane, the tone armbeing pivoted to swing vertically about a pivot I 5I applied to the yokeportion of an upright stem I52 journaled in a step bearing I53 of thepost I58, this vertical swinging of the tone arm being necessary inbringing it reproducing needle I54 into engagement with a record forplay or out of engagement therewith when swingins-outwardly over therecord after play. Also fulcrumed on the pivot I5I is alaterally-swinging depending brace or stay bar I55 which moves with thetone arm and which is provided at its lower end with an adjusting screwI58 in contact at its inner end with a laterally-swinging pendant backplate or yoke I51 disposed alongside the post I58 and pivoted at I58 tothe upper end of the latter as shown in Figures 12 and 14. Mounted onthe post adjoining this pendant back plate to turn thereon, is a cammember or sleeve I58 which rides against the inner face of this backplate and thereby causes the latter to swing in a direction away from ortoward the post to in turn effect, through the medium of the stay barI55, the raising or lowering of the tone arm out of or into engagementwith the record. In the non-play or outwardly-swung position of the tonearm, shown in Figure 14, the cam member I58 is abutting the back plateto support the tone arm in its elevated position. Depending from theupper or yoke portion of the tone arm stem I52 in adjoining relation tothe stay bar I55 is a substantially L-shaped bar I 88 which likewisemoves with the tone arm and against the lower end of which asubstantially radial lug I6I projecting from the cam member I59 isadapted to abut, so that when motion is transmitted to this cam memberits lug I 8| encounters the horizontal portion of the L-shaped bar I88and causes the tone arm to swing outwardly to its initial non-playposition after a given record has been played. The means fortransaaaasee mitting motion to the cam member for controlling the returnswinging movement of the tone arm to its inoperative position, and at atime prior to that when the cylindrical cam 6I functions to contact thecross levers 13, 16 to lower the record-supporting fingers and restorthe split portion of the stack onto the turntable, consists of ahorizontally-swinging lever I62 pivoted at I63 on the platform 36 andcarrying a pin or roller I64 engaging an inwardly and outwardly directedcam groove I65 formed in the lower flanged portion I66 oi thecylindrical cam II. The outer end of the lever I62 is connected by a.link I61 to an arm I66 projecting from the cam member I59. During playposition, the cam groove I65 is disposed as shown in Figure 3,

wherein the lever-pin I66 is located at the crotch or centrally betweenthe outwardly diverging branches I65", I65 of such cam-groove. When therecord has completed its play, then motion is transmitted to thecylindrical cam l l and the lever I62 is immediately swung outwardly bythe trailing or upper branch I65- (viewing Figure 3) of the cam-grooveI65 to cause the tone arm post cam member I59 to swing in acounterclockwise direction, thereby rocking the pendant back plate I51outwardly, elevating the tone arm from engagement with the record andultimately swinging the tone arm outwardly to a position clear or therecord stack and at one side of the turntable, this position or theparts being shown in Figure 14 and by dotted lines in Figure 15. Thetone arm is held in this outwardly-swung position by reason of the leverI62 engaging the main or circular portion of the cam-groove I65, and isnot released again until another record has been selected and set inposition for play, at which time the lever-pin I66 enters the leadingportion I65 of the cam-groove and thereby turns the tone arm post cammember I59 in a clockwise direction to cause its radial lug I6I torecede from the bar I66 and hence allow the tone arm to swing inwardly.

To compel the tone arm to swing inwardly into playing engagement withthe record, I provide a horizontally-swi g g arm I69 pivoted on astationary plate I10 projecting from the lower end of the tone armsupporting post I50 and arranged to abut at its free end against thehorizontal portion of the L-shaped bar I60, 9. spring I1I connected tothis arm tending constantly to urge the bar and the tone arm 32associated therewith to an inwardly-swung position. By thisconstruction, as the lug I6I on the cam member I 59 recedes from the barI60, the springurged arm I69 compels the tone arm to swing inwardly.

In swinging from non-play to play position the tone arm is held elevatedby the back plate I51 and cam member I59 until such time as the needleof the tone arm is immediately over the starting portion of the soundgroove of the record. This position of the tone arm is governed by agravity-actuated pawl I12 applied to a plate I13 secured to the upperportion of the stay bar I55 and adapted in the cam-engaging position ofthe back plate I51, that is, in a position supporting the tone arm inits elevated position, to abut against a stop shoulder I14 formed in theupper edge of the back'plate I51, so that when the tone arm, during itsinitial inward swing, reaches a position over the starting groove of therecord it is arrested by such pawl engaging its companion shoulder. Aspreviously stated, during the inward swing of the tone arm, the cammember I59 is swung in a direction to move its arm I6I away from theadjoining portion of the pendant bar I50 to allow the spring-actuatedarm I69 to swing the tone arm inwardly. After the tone arm is arrestedin this manner, the continued turning of the cam member I59 causes it toeventually ride oil or be removed from supporting engagement-with thependant back plate I51 and allows the tone arm to swing downward bygravity to bring its needle into playing engagement with the recordgroove. As the back plate rides oi! the cam member I59 and swingsinwardly, its upper edge bearing the pawl-engaging shoulder I16 islowered, thereby disengaging such shoulder from the pawl to allow thetree inward swing or the tone arm during playing or the record and inthis position of the parts said pawl is supported at its free end on aflange I15 projecting inwardly from the lower edge of the pawl-bearingplate I13.

When the playing of a record is completed, the tone arm serves toautomatically effect the shifting of the clutch collar 66 irom itsneutral position to clutching engagement with the worm wheel-collar 63,so as to transmit motion to the cylindrical cam 6| and restore the stackto original position in readiness to efiect the selection of the nextrecord. For this purpose I provide a vertically-swinging trip lever I16pivoted at I11 to the plate I10, the outer arm of this lever beingprovided in its top edge with a series of teeth I16 terminating in aninclined portion or tail I19. Arranged for cooperation with this triplever and particularly with the teeth and inclined portion thereof is apendant pawl I60 supported on a pin I6I projecting from the horizontalportion of the L-shaped lever I60 which moves with the tone arm. Theother arm of this trip lever I 16 is provided in its lower edge with alatching shoulder I62 against which one end of a horizontally-swinginglever I63, pivoted intermediate its ends, at I64 to the platform 30, isadapted to engage. A spring I16 normally urges the trip lever into itslatched position. Connected to the other end of the lever I 63 is a pullrod I 65 guided in a bracket I66 and terminating at its free end in ahook or depending portion I61 adapted for coupling engagement with anextension I86 of the clutch-controlling tie bar I33. A spring I69applied to this pull rod between the lever I63 and the bracket I65serves to constantly urge the same and said lever in a direction toswing the tie bar I33 from coupling engagement with the clutch-shiftinglever 69. During the playing position, the trip lever I16 is in theposition shown in Figure 12 wherein the lever I63 is in abuttingengagement with the shoulder I 62 to hold such lever and associatedparts in clutch-released position. When the playing of the record iscompleted and the needle encounters either the eccentric or spirallead-in type of groove, a movement is imparted to the tone arm whichcauses the pawl I60 to trip the lever I16 in a direction to disengageits shoulder I62 from the lever I63, whereupon the spring I69 applied tothe pull rod I65 causes the latter to move in a direction to disengagethe tie bar I33 from the clutch-controlling lever 69 to thereupon causeits spring 69 to shift the clutch collar 68 into clutching engagementwith the cylindrical cam 6i to restore the parts to their initialposition.

During the movement of the tone arm to its outward position efi ectedthrough the medium of the cam-actuated lever I62, and at the time whenthe lever-pin I64 is engaging the trailing portion I95" of the camgroove I65, I provide means for automatically restoring the lever I83 toits latched position with the tone arm trip lever I18. This meansconsists of a tappet pin I99 applied to the link I91 disposed betweenthe cam member arm I68 and the lever I82 and an adjustable trip. fingerI9I applied to the tripcontrolled lever I83, so that during the outwardswing of saidlever I62, viewing Figures 3 and 5, the tappet pinencounters the trip finger IM and causes a swinging of the lever I83 toits initial position for latching engagement behind the shoulder of thetrip lever I16. The trip finger I9! is mounted on the inner arm of thelever I83 and is adapted to be laterally adjustable, when desired,through the medium of a pin and slot connection I92.

When a record is selected for play by depressing one of the selectorrods 9I, means are provided for shifting the slidable bar I49 lengthwiseof the bail or crank I48 to bring such bar to a position in registerwith the companion selector rod engaging lever 95 in readiness torestore that lever to its initial position when the selection iscompleted. To this end a springurged horizontally-swinging lever I93 isprovided which is pivoted at its inner end at I94 to the platform 39 andwhich is connected at its outer or front end by a link I95 with theslide bar I49 to shift the latter in accordance with the swingingmovements of such lever. This lever is actuated during the rotation ofthe elevating cam 56 for raising and lowering the turntable to theheight at which the selected record is to be played, and for thispurpose a selector cam I96 is fixed on the lower end of the cam shaft 51in peripheral contact with a pin or roller I91 ap plied to the lever I93as shown in Figure 5. The turntable-elevating cam 58 and the slide barselector cam I96 are so gyrated and proportioned as to effect likestages of movement to the parts controlled, respectively, all to the endthat when a given record is selected and the turntable raised to theelevation for playing it the slide bar I49 will be accordingly shiftedto a position on the ball or crank I48 in alinement with the lever 95 ofthe selector rod 9I companion to the selected record. By thisconstruction, when a pre-selected record has been elevated to itsplaying height the slide bar I49 is simultaneously shifted on its bailand brought to rest in register with the projected lever 95 companion tothat of the depressed selector rod which was previously depressed in'selecting the record for play. In this position, the bar I49 is'in apreset position to subsequently restore the lever 95 to its initialposition, and in so doing open the companion switch 99, 99 associatedtherewith. As previously stated, the restoration of these levers 95 totheir initial switch-opening positions is accomplished automatically,during the time that the record stack is being split to form a clearanceabove the selected record to be played, through the medium of the triplever I43 actuated by the tappet I42 on the gear 95 of thestack-elevating cam shaft 82 in conjunction with the rock lever I46which. functions to rock the slide bar carrying bail I48 forwardly tobring the slide bar into engagement with the companion lever 95 torestore it and its companion switch element 98 to open position.

' In practice, this automatic phonograph is coincontrolled and includedin the circuit of the" motor 45 for operating the respective parts ofthe phonograph mechanism is a switch I98 which is coin-controlled in anyusual and well-known manner. When the patron desires to have threerecords played, he makes his corresponding selections at the pushbuttons 92 to establish the circuit of the selector mechanism and thendeposits the propercoin value, say five cents for each record, in thecoin slide applied to the phonograph, whereupon the motor circuit isthen closed at the switch I98 and remains closed until the three recordsselected have been played. Should, however, the patron insert one ormore coins in the coin slide and not make any selections at the pushbuttons, means are provided for automatically playing a number ofrecords corresponding to the coin value deposited so that the patronwill obtain the playing of records whether or not he himself makes anyselection.

In the machine shown in the drawings, twelvepush buttons 92 andcompanion switch elements 98 are provided for playing a. program oftwelve diflerent records or selections and in addition to these twelvecompanion selective units there is provided a thirteenth ornon-selective unit, that is, one unit in excess of the selective unitsborne by the machine. This additional or thirteenth non-selective unitconsists of a switch element 98 which is, in part, included in thecircuit controlled by the companion switch elements 98 and whichnormally is in contact with v the common switch element 99. However, inconnection with this non-selective switch element 98 there is nocompanion selector rod or push button, such switch element, as beforestated, being normally closed and is automatically opened whenever anyone or more of the companion selective switch elements 98 have beenclosed by reason of selections being made at the push buttons. As shownin Figure 16, the switch element 98 is connected by a wire I 99 with anarcuate contact segment 299 applied to the lower portion of theinsulating panel I9I and arranged on the arc of a circle of lessdiameter than the are on which the terminals I9I are arranged. Therevolvable contact or wiper member I93 includes a second arm 29I whichis substantially diametrically opposed to the companion arm I92 thereofcooperating with the terminals I9I and which cooperates with the contactsegment 299. The latter is so disposed relative to the spaced terminalsI9I as to always have contact with the revolving switch arm 29I when thecompanion switch arm I92 is traveling in the operating range of saidterminals I9I.

Connected to and, extending forwardly from the upper end of the switchelement 99* is a forked-member 292 which embraces a verticallyswingingbail or crank 293 pivotally supported in end walls of the frame I49between the switch elements 98 and the button-controlled levers 95. Thisbail normally bears at its front side against the opposing inner edgesof the levers 95 and in the upright or non-projected position of thelatter the bail assumes a slightly rearwardlyinclined position as shownin Figure 7, at which time the several selective switch elements 98 areopen and the non-selective switch element 98 is closed by its inherentspring tension. In this position, the crotch of the forked member 292abuts the'rear side of the bail 293. By this construction, when any oneofthe levers 95 is pushed inwardly to close a companion switch element98 as a result of a patron making a corresponding selection at thepush-buttons 92, the bail 293 is swung forwardly by that lever to theposition shown by dotted lines in Figure 9 to simultaaasasse neouslyopen the non-selective switch element ll through the medium the forkedconnection 202. 7

When it is desired to cancel a selection once made, this may be donethrough a cancelling rod or button 204 guided in the iace plate 82alongside the buttons 82 and operatively engaged at its inner end to onearm of a rock lever 20!, the other arm of such lever being connected bya spring 206 with a crank arm 201 ilxed on the adjoining end or journalof the bail or crank 20!. Thus, by depressing the cancelling button 2",after a selection has been made and wherein the bail and the crank arm201 are in their forwardhr-projected positions, these parts will berestored to their initial positions and the companion selective switchelement 98 will be opened and the non-selective switch element will beautomatically closed.

In Figures 17-22, inclusive, there is shown a modified form ofrecord-supporting tray as well as a modification of the engaging ilngerswhich cooperate therewith for eil'ecting the splitting of therecord-stack for playing a selected record. The trays 208, in thisinstance, are substantially pan-shaped and each has a substantiallyupright cylindrical wall 208 and an annular, outwardlyextending flange210 at the base thereof. In the stacked position of the trays, the baseor one rests upon the top edge of the cylindrical wall of the oneimmediately below it, thereby leaving uniformly-spaced annular groovesor channels 2 between adjoining trays for receiving the elevatingfingers.

Each of the elevating fingers, seen in Figures 17, 18 and 19, consistsof a post 2| 2 rising from each end of its companion rock bar H andhaving a freely rotatable record-tray engaging member 2|! at its upperend, such member being free to rotate from contact with the trays whenits post is swung inwardly into engaging relation therewith. At itslower end this rotatable member has an outwardly-facing flange 2 whichis adapted to enter the channels 2 between the trays for supportingengagement with that tray immediately above the one selected for play.Figure 17 shows the normal relationship existing between the turntable33 and the elevating posts when the phonograph is at rest orinoperative; Figure 18 shows the relationship existing when theturntable is elevated to a record-selecting position; and Figure 19shows the relationship of these parts when the record-stack has beensplit to provide the operating clearance for the tone arm when playingthe selected record.

Referring to the modifications of the invention shown in Figures 23, 24and 25, the tone arm 32 and associated parts, including the supportingpost I50, are mounted in a hollow boss or extension 2!!) formed in thebase plate US which supports the working parts of the phonographmechanism. Borne by this extension are suitable electric plugs orconnectors 2H and H8, whereby the phonograph can be readily connected toa service line and to a coin-controlled magazine switch, respectively.The connector 2H is of the threeway type and, as shown in'Figure 25, thehigh voltage leads 2|! and 220 are connected to the motor 45 while thelead 22l as well as the continuation of the lead 220 are connected to atransiormer 222 whereby low voltage is used to operate the selectormechanism and other parts of the phonograph.
